Weathering Orks

So I started an Orks army. It's been coming together nicely so far. I just wanted to talk for a minute about weathering. I've tried a couple of different weathering techniques with these guys so far and I'll tell you which one I like best.

First:

For this one, I made some battle damage on the front plate with a modelling knife, then basecoated with scab red. Then I brought all of the non damaged parts up with blood red leaving scab red around the bullet holes. Then I just painted the bullet holes with boltgun metal. The mud on the front was done by super gluing sand all over the front of the buggy.

Second:

This time, after painting the whole tank with mechrite followed by blood red, I applied chaos black to the hard edges using a torn up piece of blister foam. Then I applied boltgun metal via the same method. I like this method better than the first and it is reeeally easy to do, but I think it looks a bit sloppy, so while it's not a bad method, I don't think I'll be using it again (although maybe I'll decide otherwise).

Third:

This time, after painting the wheel well with fancy flames, I simply painted on some chipped looking boltgun metal. This doesn't look very good at first, but after washing the model (I use devlan mud or gryphon sepia, I like to change it up from model to model) the boltgun metal kind of pops and looks nice. I like this method of weathering best of the ones I've tried so far. I've been using it on boyz shoulderpads, here's a nob I used it on.

Anyhow, the third method is pretty easy and I think looks pretty good, just make sure to give the model the wash as it improves the look greatly.
